This would appear to fail the unit tests.  =-)

(Unless the tests are wrong themselves, which has happened before
on occasion.  But the regexp above seems to produce "extra" null
fields. . .  I think it's the zero-or-more effectively matching
on a comma - because it implies a zero-width match is OK. . . ?)
